The general use is:

user = UsernameValidator([4], #length
                         [1], #lower-case chars range
                         [1], #upper-case chars range
                         [1,3], #numbers range
                         [0,0], #symbols range

The use of range is:

[2, 5] # minimum 2, maximum 5 characters
[1] # at least one
[0] # not necessary, not denied
[0, 4] # not necessary, maximum 5 characters
[0, 0] # denied

###Validation In order to validate a text (Username or password) you have to call the method Validator.verify(text)
It returns two objects:

1. a boolean (True if the text is valid, False if there is one or more errors)
2. a string, that can be:
   • '' empty, if there are no errors
   • 'length' if the text is too short or too long
   • 'lower' if there are too few or too many lower-case characters
   • 'upper' if there are too few or too many upper-case characters
   • 'digit' if there are too few or too many numbers
   • 'symbols' if there are too few or too many allowed symbols

from Credentials_Validator import UsernameValidator

user = UsernameValidator([4, 10], [1], [2], [0], [1],)

is_valid, error = user.verify('PasswOrd!')
print((is_valid, error))
#returns (True, '')

is_valid, error = user.verify('PasswOrd3')
print((is_valid, error))
#returns (False, 'symbols')

is_valid, error = user.verify('Password!')
print((is_valid, error))
#returns (False, 'upper')

is_valid, error = user.verify('th1sPasswOrdist00long')
print((is_valid, error))
#returns (False, 'length')

###Customization
The default symbols are: !"#$%&'()*+,-./:;<=>?@[\]^_{|}~

You can customize the simbols by adding your custom list (string):

from Credentials_Validator import UsernameValidator

my_symbols = '!?$%&@#'

user = UsernameValidator([4, 10], [1], [1], [0], [1], symbols_list=my_symbols)
